Computer Programming C Laboratory: Standard Libraries and Header Files in C Programs
C Program to print the value using preprocessors
The 'C' Preprocessor - Standard Libraries and Header Files in C Programs
C Program to print the value using preprocessors.
/* C Program to illustrate preprocessors*/
#define USD 1 /* macro substitution */
#define UKP 1
#include <stdio.h>
#ifdef USD
#define currency_rate 46 /* macro substitution */
#endif
#ifdef UKP
#define currency_rate 100 /* macro substitution */
#endif
void main()
{
int rs; /* Local definition */
rs = 10* currency_rate;
printf ("The value of rs is: %d\n", rs);
getch();
} /* main */
OUTPUT:
The value of rs is: 1000
EXPLANATION: This program prints equivalent rupees value for the dollar amount, the currency rate and all defined as preprocessor.
